问题
I'm writing a custom Heroku buildpack (heroku-buildpack-fantom) for Fantom, and as part of the compile script I've downloaded a .zip file (from a language vendor), but how do I unzip it?
unzip is not a recognised command.
gunzip exists but I can't use it to unzip .zip files.
What am I missing?
回答1:
Even though (by default) Linux does not come pre-installed with unzip, the Heroku dyno does have a jar command. So the following works okay:
> jar xf wotever.zip
回答2:
Be sure to run the 'file' command on it. I got a .zip file from SourceForge that was actually bzip2 encoded and Heroku has both the bunzip2 decoder and the -j (--bzip2) option on tar to handle it.
